Hyperthyroidism (goiter)

My doctor said that my thyroid glands are swollen. They have been that way for about 10 months now. They want to remove them. Is this the only option? The doctor said that I will always have to stayon the medication if they remove them. I am not doing good with the medication right now. Is therea chance that my thyroid glands will return to normal with the use of the correct medication?Desperately seeking help.
